i recently took 13 members of my family on this cruise. (ages 8-65) I had taken celebrity before and liked the food and the ambiance of the ship. We traveled AQUA class last time but because there were 3 or more in each room we could not take AQUA class but paid extra for concierge class.
We had balcony rooms on deck 10 which were near the library. We were close to the pool and cafeteria so these were good rooms. The staff in the rooms were helpful for the most part and we did not need to bother them for many things. One family member had a broken wall on the deck and it took 2 days for it to be fixed. This was not a good way to start our cruise. They did give them dinner at a specialty restaurant and a bottle of wine to make up for it but at 2 in the morning you don't care about those things. Otherwise, the rooms were good and as for the concierge part we never saw our guy the whole cruise. Our rooms were clean and we had all we needed but had we needed anything not sure we would have found him.
Dinner:
Good size room and bathroom for three people. No noise.
